Abstract :A Linear Fresnel reflector Solar concentrating (LFRSC) system consists of number of flat mirrors kept on a horizontal base at a certain tilted angles, which reflects the sun’s rays into a central receiver held above them. In this paper, we have made a comparative study between two different LFRSC systems with tubular absorber. The first LFRSC system has reflector plates of same width and the second system has reflector plates of varying width. The objective of this paper is to find the optimum design parameters for each case and to find the best between the two the systems. By varying various design parameters like width of the reflector plates, shift between the plates, the height of the receiver tube from the reflector plane and diameter of the receiver tube, calculations were done. The solar flux is considered to be a constant of 0.6 kW/m2 and the reflector plates are assumed to be made of glass (Ï=0.98). Concentration ratio and concentrated flux are determined for each case and graphs are plotted for comparison. Results show that the LFRSC system with same width plates has better efficiency (C.P = 3.15 kW and C.R= 103.3) than those with varying width plates, while considering optimum design parameters of height from reflector plane, width of the plates and diameter of the receiver tube as 1.5 m, 0.03 m and 0.015 m respectively for a certain range considered.
